Abstract: An apparatus for balancing a fan or other spinning product may comprise a motor for spinning the fan, an accelerometer for gathering sampling data from the fan while it is spinning, a laser source, a laser redirection platform comprising a spinning mirror configured to track the rotational speed of the spinning fan, and a control module. The fan and laser redirection platform may each have an index hole for tracking, using respective photocell transmitters and receivers, rotational speed and phase. The control module may direct the fan motor to spin up the fan, collect balance data, and determine a location on the fan for burning a hole to correct imbalance. The control module may direct the laser redirection platform to spin at the same rpm as the fan, and such that a laser redirection mirror directs a laser beam from the laser source toward the target burn location on the fan.

Abstract: A process and apparatus which reduces the fines in a liquid discharge stream and/or increases the dryness of a solids discharge stream while under a pressure equal to or greater than the vapor pressure of the liquid. There is provided a process for separating particles such as polyethylene terephthalate or polyethylene naphthalate from a liquid in a slurry comprising: a. feeding a slurry comprising solid particles and a liquid into a within a separation zone maintained at a pressure equal to or greater than the vapor pressure of the liquid; b.

Abstract: A bicycle support rack to suspend bicycles from a garage or other structure ceiling and including an electric powered winch with means to secure the winch to the ceiling, a support frame arranged to be raised to the ceiling with the winch and pressed against the ceiling by a lift frame having hooks thereon for attachment of bicycles to be suspended and control means to operate the winch to raise and lower the lift frame while said lift frame is connected to and suspended beneath the secured support frame.

Abstract: The present invention relates to a process by which a carboxylic acid/diol mixture is obtained from a carboxylic acid/solvent slurry without isolation of a substantially dry carboxylic acid solid. More specifically, the present invention relates to a process by which a terephthalic acid/ethylene glycol mixture is obtained from a terephthalic acid/solvent slurry without isolation of a substantially dry terephthalic acid solid.
